摘要(Abstract)：

利用定向爆破成功地拆除复杂环境中的一座水塔。倒塌方向上空间的宽度仅为水箱直径的两倍。通过一系列技术措施 ,如较小的切口长度、较低的切口位置、较大的切口高度、开凿定向窗以及合理的爆破参数 ,使水塔精确地按设计的方向倾倒 ,并消除了水塔倒塌时的后坐现象。地面铺放软物质 ,减小了塔顶水箱落地时的冲击震动效应。切口位置的严密覆盖 ,有效地阻挡了飞石。倒塌方向两侧的建筑物没有受到任何损坏 ,爆破达到了预期目的
A water tower in complicated environment was successfully demolished by use of directional blasting The width of space in collapse direction is only twice as large as the diameter of water tank Through a series of technological measures such as shorter cut,lower cut position,increased cut height,opened directional windows and reasonable blasting parameters,the water tower was made accurately to collapse in predetermined direction and the recoil on water tower collapsing was eliminated The shock at the moment of the falling of water tank on top of the tower was damped by laying of the soft materials on the ground The close covering of cut position made flying rocks stopped effectively Any of buildings on two sides of the collapsing direction was not damaged The predicted blasting result had been achieved
